FRANK A. DICKINSON, OF PHILADELPHIA, PENNSYLVANIA.

PACKING-RING OR GASKET.

T 0 all whom it may concern:

Be it known that I, FRANK A. DICKINSON, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inPacking-Rings or Gaskets, of which the following is a specification.

My invention relates to improvements in packing rings or gaskets, theobject of the invention being to provide an improved device of thischaracter which may be utilized in practically all places where tightpacking rings are desired, and which will efiectually resist the passageof steam or other fluid, and lubricate as well.

With this and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts, as will be more fully hereinafter described and pointed out inthe claims.

In the accompanying drawings: Figure 1, is a plan View of my improvedpacking ring or gasket. Fig. 2, is a view in section on the line 22 ofFig. 1, and Fig. 3, is a view in section on the line 83 of Fig. 1.

In constructing my improved packing ring or gasket, I employ a thinmetal ring 1, which is preferably of copper or some relatively softmetal, and is perforated as shown at 2 for the reception of bindingwires or threads 8, which serve to securely hold a winding 4 of asbestosgraphite treated cord, wound thereon. In other words, upon the said ring1, the cord 4 is wound, and is secured to the ring by means of thebinding wires or threads 3. The ring is then flattened and treated withgraphite, so that it becomes a lubricating packing ring, as well as onecapable of forming a tight joint. The binding wires or threads 3 arecrossed through each opening and passed backwardly and forwardly asshown most clearly in Fig. 1, so as to of fectually bind the cord 4: ona metal ring.
